1. Start production and printing without first pressing the ink to maintain the print head. When the machine is in standby for more than half an hour, the surface of the print head will appear slightly dry, so it is necessary to press the ink before printing. This can ensure that the print head can reach the best printing state. It can reduce the printing wire drawing, color difference and other problems. At the same time, it is recommended to press the ink once every 2-3 hours during the printing production process to maintain the nozzle and reduce the loss.
2. Printing problems: During the printing process, if the height of the material is incorrect, it is easy to cause quality problems such as offset of the printing screen and floating ink.
3. The distance between the nozzle and the surface of the product is too close, it is easy to cause the nozzle to rub against the surface of the product, damage the product and damage the nozzle at the same time.
4. The phenomenon of ink dripping during the printing process is due to the damage of the nozzle, resulting in air leakage of the filter membrane.
Therefore, when a novice operates a UV printer, it is necessary to place the items flat, and keep a distance of 2-3 mm between the product and the print head to avoid collision with the print head. Shitong UV printer is equipped with a print head anti-collision system, which will automatically print when it encounters a collision. At the same time, it also has an automatic height measuring system, which can automatically detect the printing height, which greatly guarantees the normal operation of the machine and reduces losses.
